Greetings all-
I'm managing an AlphaServer 4100 with about 31,000 accounts that uses NIS
(yp) to share
the password and email aliases folders. We are using C2 security, and have
Tru64 4.0d.
During the day, when we have about 120 interactive session, 300 imap
sessions, and a flood of
sendmail processes, we sometimes have a hang which prevents new logins and
stops system activity.
The 'ps' command stops working, and typing 'ypcat passwd' just hangs. While
I thought I had to reboot
the system to fix the problem, I first killed off all the user processes on
the box. To my suprise,
that seemd to fix everything, and all system services came back to life ( I
have a killalluser script
that makes doing this easy ). People started logging in again, we got
bunches of imap, and the
ypcat command worked.
This has actually happened twice, and both times killing off the users seemed
to fix the problem.
Does anyone know if this is a "known problem" whenever NIS starts getting a
lot of requests, or do
I just have something haywire on my box? Am I missing a patch? Does anyone
else run a big
installation with a lot of NIS hits throughtout the day that might match this
configuration and
can testify that all is well with NIS? I just want to know that I'm chasing
the right thing.
We are only running with patch kit 5, because this is a TruCluster system and
doing the patches
with all these users is a bear ( I know, its no excuse -- we're going to 5.1
on all these boxes soon,
so it won't matter anywho).
Thanks for any info on this.
